IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 17,430, dated June 2, 1857.

To all whom it may concern:

Be it known that I, JOHN S. HALL, of West Manchester, county of Allegheny, in the State of Pennsylvania, have invented a new and useful Improvement in Hillside and Horizontal' Reversible Plows and I do hereby declare that the following is a full and exact description thereof, reference beinghad to the accompanying drawings, and to the letters of referenee marked thereon.

The nature of my invention consists in the peculiar construction of the mold-board and adjustment of the beam, together with a hollow landside and movable bottom piece, as hereinafter described, the whole forming or constituting a more simple, economical, and effective plow than has been before known or used.

To enable others skilled in the art to make and use my improvement, I will proceed to describe its construction and operation.

In the accompanyingdrawings, making part of this specification, Figures 1, 2, 3, &c., represent elevations and detail views,as explained in reference to figures on said drawings.

A is the double reversible mold board, which is so formed that when on either side of the landside the board-is as perfect in its operation as that of a stationary mold-board plow, which improvement I accomplish by extending the outlet said mold-boardin the form of ears, as represented in the drawings, of such length and form as that when a line in Fig. 1 is drawn, cutting off that part of theboard H which is not in use, the part A or actual :mold-board is framed as shown, or extending backward and downward as far as is required to properly hold and lay the furrow.

I am aware that there are revolving or reversible plows with ears formed on the end of the mold-board; butthey are dissimilar to mine, as they do not accomplish the end for which mine are designed, but are formed merely by cutting away a slight portion of the center of the back end of the board, which could be of no service, and are the result of accident, and of such form and capacity as to be of no use.

The mold-board A is pivoted to the front and back end of the landside, near its bottom, in the usual manner, so thatit may be reversed from one side to the other of the landside, and

is secured in either position by means of the. hook at, pivoted or stapled at c on the rear of the landside and hooking around or clasping the brace-rod 0. (Best seen at Fig. 3.)

B is the landside, the outline of which is somewhat similar to those now in existence. The bottom of the landside is formed, as represented at Fig. 7 with concavities or recesses jj, which are adapted to the flanges h h on the bottom piece, F. (Best seen at Fig. 5.)

F is the movable bottom piece, which is formed as represented, as shown at Figs. 5, 9, 10, and 11, which views are a vertical section through the center, side, top, and bottom view of said piece F. Said bottom piece, with its flanges h h, is placed upon the bottom of the landside, which is made of the peculiar form, with recesses j j adapted to receive its flanges h h, and is secured to said landside by means of a bolt and nut, g. It will be readily seen that said bottom piece, when in its place, constitutes the entire bottom of the landside. (See Fig. 4.) The great value of the improvement consists in economy-that is to say, when the bottom of the landside is worn out the piece F is removed and replaced by one similar with little expense and comparatively no loss of time, whereas without such a movable bottom piece the entire landside would have to be renewed or repaired at great expense and much loss of time.

G is a curved projection around the top of landside, forming a shoulder for the beam 0 to rest and move in, and havingin it the oblique slots z i, through which the bolts on I) pass for securing the beam 0 to the landside top G. The beam 0 fits and moves in the curved shoulder or are 0 (see Fig. 1) in the top of the landside, and bybeing vibrated in said are has its draft end raised or lowered as may be desired, as shown by thedouble position of said beam in black and red lines in Fig. 1. When adjusted to any required position the beam is secured in said position by means of the bolts a b passing through said beam and through the slots it in the top of the landside or piece G. It will be observed that the slots *5 i are so formed or placed in the landsidetop that any draft or power exerted upon the beam 0 in a horizontal line has little or 'no tendency to slipthe bolts a b in their slots t i, as all strain is brought indirectly upon the sides of said slots it, as represented by the red lines of draft w w and y y, Fig. 4:.

When the plow is to be used the mold-board and share are placed on. either side of the landside and there secured by means of the hook (I, as before described; and the beam 0, being adjusted to any required position by slipping itin its are or bearin g, is secured by means of the bolts to b and their nuts. The movable bottom piece being secured to the bottom of the landside, the plow is then operated as any other.

When the bottom of'the landside wears out the piece F is removed and one similar put in its place with little expense and a loss of little or no time.

Having thus explained the construction of my improvement and shown its advantages, what 1 claim as my invention, and desire to secure by Letters Patent, is-

vibratingithe beam in a circular bearing in the landside, together with the oblique adjusting and securing slots 75 i, the whole combined and arranged substantially as described ,whereby the draft end of the beam may be vertically adjusted and the beam so secured to the landside as that'it is impossible for the former to slip. r

In testimony whereof I have hereunto set my hand and seal;
